Laser
Hmm… I suspect Travis Cooke will know the answer to this: I wonder if everything on these laserdiscs is available on the BlueRay collectors editions?
I remember the Aliens Laserdisc has one track that is hundreds of set pictures (one picture per frame, so you have to do frame by frame on a CLV frame capable player).
[Yes, these are Laserdiscs, the single coolest form factor ever invented for video.]
